Application September 8, 1931, Serial No. 561,709 Renewed July- 13, 1933 2 Claims.

My invention relates to a typewriter mountin device applicable particularly to oifice desks .but also applicable for installment on walls, cabinets or any place where available space is limited for a. typewriter, adding machine, check writer or similar machines.

The main object is to provide a device of the class stated and comprising a small number of parts, having ready accessibility, and available for use at any time with a minimum of effort for putting it in operative position. The primary object being to provide a typewriter attachment for office desks, I have illustrated the device mounted in a desk of said kind.

In the accompanying drawing,-

Fig. 1 is a front view of an oilice desk showing approximately one-half of a desk and the typewriter attachment in operative position.

Fig. 2 is a vertical sectional elevation, in slightly '2 reduced scale, as on line 2-2 in Fig. 1 revealing an end wall of a desk and my device in lowered position ready to be rolled into the desk opening.

Fig. 3 is a horizontal sectional view just below the desk top, as on line 33 in Fig. 2, including 2 a top view of the attachment in operative position, and additionally the position of a desired type of typewriter table bracket supporting the free edge part of my typewriter table supported in horizontal plane exteriorly of the desk-front.

In Figs. 1 and 2 a typewriter is designated in dotted lines only.

Referring to the drawing by reference numerals I have illustrated approm'mately the left half of an ofiice desk of which 5 is the top, 6 and 7 respec- 1 tively the front and rear corner posts thereof, and 8 and 9 respectively the front and rear inner left posts.

To the right of the latter the desk is open under its top, as usual, for the legs of the person seated 9- at such desk, said opening designated 10 in Fig. 1. 11 and 12 are respectively the outer and inner transverse panels of the desk and 13 the rear panel. 44 is the floor or base of the left side compartment of the desk, thus formed by the re- 5 ,spective panels, the compartment thus being open forwardly and immediately to the left (or right) of the person seated at the desk. In desks of the type shown there is usually a tier of dnawens (not shown) at one side and the other side has 5 the compartment described.

My device comprises horizontal metal rail 14 preferably a channel iron, the flanges of which have their edges bent inwardly to guide rollers 15 suitably, rotatably mounted in pairs on a hori- .;zontal slidable carriage or support bar 16. The

said rollers engage the upper and lower flanges of the fixed rail 14, the bar 16 being preferably close thereto and parallel. The fixed rail 14 may be secured to a wall or other stationary upright object but are illustrated as fixed to the front and rear outer posts 6-7 of a desk, parallel to its top and just below the latter, within the compartment, the latter being designated A in all the views. The bar 16 is of course movable into the compartment so as to be hidden from View and movable outwardly also so that approximately its outer half projects from the compartment. On said latter half, and at the muse edge of bar 16 is a secured hinge means 18, hingedly secured also to a typewriter board 19 suitably braced if necessary by cleats 20 (see Fig. 1) on its under side. This board 19 is preferably quadrangular and about 14 by 16 inches in size. 011 top of the board is suitably fixed, as by screws 21 through the board, a typewriter 22 shown only in dotted lines.

1'? in Figs. 1 and 3 is a pivoted upright bracket, pivotally mounted in two vertically spaced hinge members 23 fixed on post 8, the upper part of said bracket comprising a horizontal arm 17A located at such height that said arm may be swung under the board 19 and supports it in horizontal plane when the latter is in operative position and holding the typewriter in position for use near the operator seated at the desk. Obviously, the bracket may be swung inwardly toward panel 12 (see Fig. 3) to let the board 19 down, the typewriter then being of course in hanging position with the board as shown in Fig. 2, and the operator merely pushes the device inwardly, the rollers 15 riding in rail 14, until the typewriter is completely within the compartment A as designated by dotted outline 19X in Fig. 2.

Suitable stop means such as a pin 25 (Fig. 3) fixed in the upper flange of rail 14 must be provided to limit outward movement of the carriage.

Because of all the weight on one side only of board 19 it is obvious that the latter would not hang vertically. Therefore I have provided guide means comprising an elongated bar 26 fixed to the under side of board 19 and parallel to rail 16, this bar projecting inwardly and carrying a roller 27 at its inner extremity. 28 is a secondary rail fixed in parallel relation to and below rail 14. in approximately a common vertical plane therewith. The roller 27 contacts with the inner 165 face of said rail 28 continuously when the board 19 is in lowered position.

I have now fully described my invention in its preferred form, its use having been clearly revealed in the specification simultaneously.

Modifications in details of construction, proportions of parts, etc., are of course governed more or less by the available space. It is obvious that the use of this device is not limited to desks, but it may be mounted as stated on walls, partitions or any suitable fixed element in such places as where the typewriter, or computing machine may be let down, after use, and rolled on the carriage to a position where it will be out of the way but always ready for use.

I claim:

1. In a supporting device for typewriters and the like adapted to be mounted within and between parallel transverse walls of a desk compartment and under the top of such desk; said supporting device comprising an upper main horizontal rail fixed to one of said walls, a secondary guide rail mounted parallel to and below said main rail, a platform carriage slidably mounted and guided by the main rail and comprising a horizontal bar with suitable roller means engaging the main rail, a platform hingedly secured to the outer portion of said bar and suspended therefrom when the bar is within the compartment and adjacent a wall thereof, a fixed bar projecting inwardly from the under side of said platform and provided at its inner end with roller means adapted to engage the secondary rail when the platform is suspended as described, means for securing a typewriter or the like to one side of said platform, and bracket means hingedly secured to the opposite wall of said compartment and adapted to be swung under the said platform when the latter is raised to horizontal plane exteriorly of the compartment.

2. The structure specified in claim 1 in which said latter hinged means comprises a bracket with an upper horizontal arm suitably braced and adapted to swing in a horizontal plane to a position with said arm contacting under the raised platform exteriorly of the compartment, and said bracket further adapted to be swung into the compartment parallel to the wall thereof opposite the wall having the rails described.
